Nutrition is a fundamental determinant of health, and its impact is particularly profound at the population level. This book explores the relationships between diet, disease prevention, and health promotion across diverse populations. It addresses food security, dietary assessment tools, public nutrition policies, and interventions. Special topics examine nutritional challenges in vulnerable populations and across life stages. Emphasis is placed on global health nutrition, public campaigns, and evidence-based dietary guidelines.
